目的：探讨社区老年人口腔功能与骨质疏松症分期的关系。方法：对65岁及以上社区老年人进行横断面研究。我们使用最大舌压测量口腔肌肉力量，使用口腔直肠运动测量口腔肌肉表现，并使用进食评估工具测量主观吞咽困难。我们测量了骨骼肌质量和功能以及其他变量。所有参与者被分成4组(正常、节前、经期和骨质疏松症)，使用一种算法，该算法通过骨骼肌特征确定骨质疏松症的分期。结果：共纳入245名受试者，中位年龄81.0岁[75.0-85.0]。正常受试者为48.6%(n=119)，月经前期者为9.4%(n=23)，月经停滞者为30.2%(n=74)，骨质疏松者为11.8%(n=29)。骨质疏松症和月经过少组的最大舌压和口腔蠕动明显低于正常组。在多因素分析中，在调整了年龄后，骨质疏松症和月经迟缓组的最大舌压和口腔排空运动显著低于正常组。结论：在本研究中，骨质疏松症和月经迟缓的参与者表现出低的口腔功能，根据骨质疏松症的进展，口腔功能和骨骼肌也有类似的趋势。未来的研究应该阐明吞咽相关肌肉的特征，包括肌肉质量、力量和在每个石棺减少阶段的表现。
Purpose: To examine the relationship between oral function and sarcopenia staging, including dynapenia and presarcopenia, in community-dwelling older adults.Methods: A cross-sectional study was performed in community-dwelling older women aged 65 years and above. We measured oral muscle strength using maximum tongue pressure, oral muscle performance using oral diadochokinesis, and subjective swallowing difficulties using the Eating Assessment Tool. We measured skeletal muscle mass and function and other variables. All participants were divided into 4 groups (normal, presarcopenia, dynapenia, and sarcopenia) using an algorithm that operationally defines sarcopenia staging by skeletal muscle characteristics. A general linear model was used to analyze differences in oral function among the 4 groups.Results: A total of 245 participants were enrolled (median age [IQR], 81.0 [75.0-85.0]). The proportion of normal participants and those with presarcopenia, dynapenia, and sarcopenia was 48.6% (n = 119), 9.4% (n = 23), 30.2% (n = 74), and 11.8% (n = 29), respectively. The sarcopenia and dynapenia groups had significantly lower maximum tongue pressure and oral diadochokinesis than the normal group. In the multivariate analysis, after adjusting for age, maximum tongue pressure and oral diadochokinesis were found to be significantly lower in the sarcopenia and dynapenia groups than in the normal group.Conclusions: In this study, participants with sarcopenia and dynapenia showed low oral function, and similar trends were indicated for oral function and skeletal muscle according to progression of sarcopenia staging. Future research should clarify the characteristics of swallowing-related muscles, including muscle mass, strength, and performance at each sarcopenia stage.
